Title? I don't need no stinkin' title.
Yeah, it doesn't really feel like 5E makes you make particularly hard choices, especially for wizards. Not that it's game-breaking, but the sub classes and specialization just feel like options on the exact same car. Like back when GM would release 3 versions of the same car with a different name tag on them.
So if I choose to be a blow-em-up wizard, that's great. I've chosen that path which may mean some more subtle options may not be available. Or vice versa of course.
